  3. Intrauterine Growth • Greatest length velocity at mid fetal life • Development of adipose tissue at 7 months • weight doubles in the last 2 months • Weight loss beyond 40 weeks

  4. Constrains on intrauterine growth • Uterine size • Placenta • Size of the mother

  5. Infancy • The era of changing growth rate

  6. Childhood • The era of stable growth rate

  7. Adolescence • The era of sex hormone induced shifting growth

  8. What is short stature
